New Manager Bounce/Tactical Shift

Overview

This pillar analyzes the 'new manager bounce', a common phenomenon where a soccer team's performance improves significantly in the first few games after a coaching change. It quantifies this effect to find value in short-term match prediction markets.

What It Does

The analysis compares a team's performance metrics, like points per game and expected goals (xG) differential, from the last five games under the old manager to the first five under the new one. It adjusts for the difficulty of opponents in both periods. The pillar also evaluates the new manager's historical record and tactical fit with the current squad.

Why It Matters

The market often struggles to accurately price the impact of a new manager, creating opportunities. This pillar provides a data-driven framework to separate genuine tactical improvements from simple narrative, offering a clear edge in predicting short-term results.

How It Works

First, we identify a managerial change and establish a baseline of the team's performance over the prior 5-10 matches. Next, we analyze the new manager's tactical preferences and past success in similar situations. We then project the team's performance for the upcoming 5 games, adjusting for opponent strength, to generate a probability of a performance uplift.

Methodology

The core calculation is the change in Points Per Game (PPG) and Expected Goal Difference (xGD) per 90 minutes. We use a 5-game rolling average before the change and project a 5-game average after. Projections are weighted based on the new manager's historical 'first 5 games' performance uplift and a Strength of Schedule (SoS) score for both periods.

Edge & Advantage

This pillar moves beyond public sentiment to quantify the bounce, identifying over or under-hyped managerial changes that the market misprices.
