Trading The NFL part 2



In this post we're going to look at some possible entry & exit points pre-match & in-play.



3) Trading Opportunities – Pre-Game

The Odds for NFL games are essentially established by Vegas (as in Las Vegas) – I use http://www.footballlocks.com/nfl_odds.shtml and reflect not a book but what Vegas thinks are prices that will attract punters. Both BF and Pinny reflect these prices but are then heavily influenced by the market – the base is Vegas.

Most NFL games are not trade-able given the poor liquidity, but the 5 televised games per week on SKY are liquid and the ladders are complete.

a)     Most movements will take place on the day of the game (unless there is a injury to the QB during the week) and are usually the result of an injury or rumour about the teams Quarter Back – the most advance information you can get is from Tweet Deck (Twitter) or the regular team injury reports available on the web – Pinny and BF will not act immediately as the information takes time to filter into the markets. Movements in respect of QB information can be upto 30/40 ticks for the better teams.

b)    Teams also have a number of key players = mostly on the Offensive side of the team – i.e. key running backs and receivers – a list of these need to be on hand during the season so that any injuries during the gameor training can be assessed for the next game. See http://www.ourlads.com/nfldepthcharts/depthchartpos/QB for a full list of starting NFL players.

c)     Review the pundits for mismatches between the BF/Vegas prices – i.e. where prices are close – say 1.9 / 2.1 – and the majority of pundits are going for the 2.1 shot –possible drift in the favourite on the day of the game.

d)    There is a coin toss 3-4 minutes before the game which will determine which side will have KO – this decision can move the price by 5 or 6 six ticks depending on the game as the receiving side has possession and has the opportunity to score. Once the KO team and receiving team is known – either lay the KO side or back the receiving side. This is a one off trade and needs to be closed out before KO – you are trying to catch the swing directly after the coin toss as prices reflect the change or continuation of possession of the football.


4) Trading Opportunities – In - Play

a ) Some golden rules:

-         As the result of the game is either win or lose – no draw – Backing one team is the same as Laying the other Team.

-         The basic principle that applies in tennis  -where you don’t back the server – is the same in most cases for the NFL - you don’t back the team in possession of the football as the market has already priced to a large extent that they will retain possession – i.e. the price will drift more if they lose possession than steam if the team retain possession.

-         As per my stats from 2014/2015 –  70% of the starting favourites will win whether they are home or away. Out of the 256 games last year – 154 starting favourites were leading at Half – Time (HT), 20 of these starting favourites ended up losing at FT, however 42 starting favourites who were losing at HT ended up winning. Be very careful when laying a starting favourite In - Play as their price may not come back.

-         The prices will be more volatile during the second half of the game with prices moving from say 1.5 to 3 with just a change in possession in the last 2-3 minutes of the game.

b)  Using the Stats to trade
         
-         In the main prices move with a change or potential change in possession. The stats to use here are First Down and Third Down performance - http://espn.go.com/nfl/statistics/team/_/stat/downs - this is the ability of the teams Offense and Defence to convert / prevent First and Third Downs – ( i.e. to retain possession the Offensive team has to move the ball 10 yards). Using the stats of both teams create the position of the expected outcome – if the offense retain possession their price will steam – if they lose possession their price will drift.

-         Fourth Downs – in the main teams will punt the ball if they have not gained 10 yards at the end of the third down. However where the team only needs 1 or 2 yards on the 4th down – or near the goal line – a team will attempt a 4th down (see link above for stats per team in 4th down conversion/preventions). Using the stats of both teams create the position of the expected outcome - if the offense retain possession their price will steam – if they lose possession their price will drift.

c)Trading Opportunities In - Play

-         The Red Zone – this is where the Offense have possession 20 yards from the Defense goal line. The prices have already anticipated that the Offense will score at least a field goal – i.e within this range the Offense is already almost guaranteed 3 points – i.e. if they fail to score at 3rd Down and they don’t need a touchdown (6+1 point) the Offense will be able to attempt a field goal from at most 38 yards  - this yardage is calculated by adding 18 yards to the yardage to where the 3rd Down has finished – i.e. if third down failed at the Defense 10 yard line – the field goal attempt will be made from the 28 yard line. The nearer the goal line the Offense can progress to - the more price will anticipate 7 points rather than 3 points. If the Offense fail to get a touchdown or lose possession the Offense price will drift significantly. Usual trade – depending on the strengths of the teams is to lay the Offense when in the red zone given that the drift will be more than the steam if the Offense fail to score a touchdown. Note that the Offense is more likely to score within the red zone – so caution needs to be exercised. The price movements in the red zone will be more volatile during the second half and in particular if the scores are close.

-         Possession in the last 2/3 minutes of the 2nd quarter approaching half-time. If the team in possession of the football with 2 minutes or less to go in the first half and also will be receiving the ball in the second half – this team has effectively 2 chances to score – this will create a significant steam in the price – as the market realises the situation.

-         The receiving team from the second half KO - following from the point above – should experience a small steam at the end of the first half as it will gain the first possession in the second half – this steam depends on the relative scores in the game – if the scores are close i.e within say 3 points the effect will be more than say where the scores are 10+ points apart. Leave this trade as late as possible as positions created too early are exposed to late scoring at the end of the half.

TRADING THE NFL



TRADING THE NFL

I kick off the blog with a great guest post regarding the intricacies of trading the NFL, written by good friend JW and edited by myself.

1 )Introduction

The NFL is made up of 32 teams, split into 2 conferences the NFC and AFC. Each conference is divided into 4 divisions of 4 teams each – North, South, East and West.

Regular Season

The regular season runs for 17weeks from September to end of December in which each team will play 16 games – one week off is scheduled for each team.

The 16 games played are scheduled each year and are calculated as:

6 games – Home and Away against the other 3 divisional opponents
4 games – On a 3 year rotational basis against other teams in the same conference
4 games – 4 teams from divisions in the other conference on a 4 year rotational basis
2 games  - 2  Intra-conference games based on a teams prior year performance

          Organisation of the Play – Offs and Super Bowl

At the end of each season 12 teams will make the Play Offs in January and ending with the Superbowl in early February.

The twelve teams are selected as follows:

8 Teams – the winners of the 8 divisions make the play offs whatever their record
4 teams – 2 teams from each conference team with the best overall regular season record.

Each of the conference teams are seeded 1 – 6 based on their regular season performance to schedule the Play – Off matches. All Play  - Off games are all intra conference apart from the Superbowl.

The Play – Offs

Wild card Weekend – The 4 teams which have made the play offs based on their performance play the 4 lowest seeded division winners. These are intra conference games – so only AFC teams will play AFC teams, etc.

Divisional Championship Weekend – the 4 winners from the Wild Card weekend will play the remaining 4 divisional winners – i.e the 2 best divisional winners from each conference have a week off during wild card weekend.

Conference Championship – the 4 teams remaining from the Divisional Championship weekend (2 from each conference) will play off to find the Conference champions for the AFC and NFC.
The Superbowl – The game between the AFC Championship winner and the NFC Championship winner.

The Draft

The owners of the National Football League teams own a franchise sold by the NFL.

A team may only have a maximum 53 players on its active roster, of which 46 can be named for a game. Of these 46 – 11 players will be on the field – depending on whether they are the Offensive or Defensive team. Any number of substitutions may be made at any time during the game.

A NFL team will be made up from Contracted players and those selected in the College Draft. The College Draft happens once a year in April / May and constitutes 7 rounds of selections made by the NFL teams. Each round consists of 32 ‘picks’ from the 32 NFL teams. The order of the ‘picks’ is determined by a NFL team’s performance the previous year – i.e the worst performing teams get first ‘pick in each round. A team may improve its ‘pick’ position with another team by trading say a
seasoned player for a more favourable ‘pick’ position.

A NFL team will also have a number of contracted players (senior players), it may also hire ‘out of contract players’ from other teams as well as trade players with other teams. These forms of contracts and trades are the only way a consistently successful team is able to compete with the poor performing teams who are obtaining the best young talent from the college draft. It should be noted here that each NFL franschise is faced with a Salary cap – i.e. for 2013 the Salary cap was $120ml – the salary bill cannot be more than this is in the financial year. In addition to the $120ml cap – franchises are also allowed a further allowance of for the new drafts – i.e. there is a separate cap for the draft picks.

Points Scoring and other anomalies.

The NFL does not like tied games – if the scores are tied after the 4th quarter – there is an automatic “Overtime” quarter of 15 mins. The first team to score a touchdown wins the game. If Team A score a field goal on its possession, Team B on its possession must score a field goal to continue the game. If after 15 mins the team are still tied – a draw is the final result. BF determines the result after overtime, the match result is declared void if a tied game. In 2014/2015 out of 256 games – there was only 1 tied game.

Touch Down – 6 points + 1 point for conversion. A team may decide to go for 2 points on conversion by running the ball into the end zone

Field Goal  - 3 points.

Safety – 2 points – when the Offensive team is tackled or downs the ball behind their goal line.

Each team is allowed three time outs per half.

At the end of each half play is suspended (general time out) with 2 minutes remaining in the half.

An Offensive team has 40 seconds to snap the ball from the end of the previous play – which means that at the end of full time if a team that is in the lead has possession it can effectively end the game with 40 seconds remaining by kneeling the ball at the next play.

2) Statistics for the NFL

There are a large number of statistics available for the NFL the most important of which are:

NFL Match Day Weekend – Pre-Game Stats

Each regular season week the NFL provide summary stats for game that weekend and during the game provide a simulation for each match. The stats go back to 2001  http://www.nfl.com/scores#. In respect of these stats I am specifically looking at overall performance of the Defense and Offense matchups as well the performance of the ‘most valuable players’ – Quarterbacks/Receivers/Rushers.

The starting Quarterback (QB)for each NFL team is of upmost importance, If any of the starting QB’s are sidelined for the better teams this will certainly cause drifts in the pre-play price . It may take a while to filter through to BF – but it will happen.

NFL Pundits– Pre – Game Stats

There are many of these I use ESPN http://espn.go.com/nfl/picks - they seem as good as any and it gives me a feel if there is a potential diversion in opinion on the favourites which tends to suggest swings pre-play.

At the start of each game week ‘The Bleacher Report’ details a review of most of the games and gives its prediction for each game.

Important Stats for In Play.

With all team games  -anything can happen so there is no ‘golden stat’ that will earn a profit – rather the stats should be used as indicators for potential entry points.

Prices will change on any of the following events:

1)    Teams lose / gain / retain possession
2)    Penalty yards for infringements
3)    Red Zone plays – where the ball is within twenty yards of the goal line.
4)    Field Goal attempt instead of a Touchdown
5)    Injury to the main QB/Receiver/Rushers
6)    At 1st and 2nd half Kick Offs.

There is a large amount of stats available on the internet for the NFL, so I suggest you just use one as you can get buried in stats. The most important stats from a trading perspective cover items 1), 2) and 3) above. These stats cover:

1)    Number of first downs gained and allowed in the season
2)    % of 3rd down conversions gained and allowed in the season
3)    % of 4th down conversions gained and allowed in the season
4)    Penalty yards gained / allowed in the season

Stats on the above for each NFL team  - split for Offense (gained ) and for Defense (allowed) can be found at: http://espn.go.com/nfl/statistics/team/_/stat/downs.

Use of these stats will be clearer once we consider the different trading opportunities / strategies but that is for another post.
