Pre-Peak Value Efficiency (PPVE)
Identifies pre-peak players offering exceptional value relative to their age bracket. Higher PPVE = better value.
Understanding Pre-Peak Value Efficiency (PPVE)
SC Braga's Gorby at 23 years old has the highest Pre-Peak Value Efficiency at 7.00×. That means Gorby is valued 7.00× higher than the median player in the 21-23 age bracket-representing exceptional value before reaching peak age.
In second is FC Famalicão's Mathias de Amorim, who is 21 years old, with a 6.00× PPVE. Third is Diego Rodrigues of SC Braga, who is 21 years old with a 4.50× PPVE.
How PPVE is calculated: PPVE compares a player's current market value to the median value of all players in their age bracket. A PPVE of 7.00× means the player is worth 600% more than typical players their age-making them high-value targets before they reach peak value.
PPVE by Age Bracket

Return-to-Peak Potential (RPP)
Recovery potential from current value to forecasted peak. Shows how much upside remains for players approaching their prime.
Understanding Return-to-Peak Potential (RPP)
FC Porto's Victor Froholdt at 20 years old has the highest Return-to-Peak Potential at +35%. That means Victor Froholdt is projected to appreciate 35% as they reach their peak age in 6 years-representing significant upside before entering their prime.
In second is FC Arouca's Taichi Fukui, who is 21 years old, with a +30% RPP (5 years to peak). Third is Diego Rodrigues of SC Braga, who is 21 years old with a +30% RPP (5 years to peak).
How RPP is calculated: RPP compares a player's current market value to their forecasted peak value, calculating the percentage appreciation potential. A 35% RPP means the player is expected to gain 35% value as they enter their prime-making them excellent growth investments.
Recovery Potential by Player
| Rank | Player | Age | Years to Peak | Current | Peak Forecast | RPP % |

Risk-Adjusted Upside (RAU)
Upside potential weighted against forecast uncertainty. Higher RAU = better risk-reward profile.
Understanding Risk-Adjusted Upside (RAU)
FC Porto's Victor Froholdt has the highest Risk-Adjusted Upside at 46.3. That means Victor Froholdt has 15% upside potential with only 0% forecast uncertainty-representing excellent risk-reward for value appreciation.
In second is FC Famalicão's Mathias de Amorim with a 33.7 RAU (10% upside, 0% uncertainty). Third is Marcos Peña of FC Famalicão with a 33.7 RAU (10% upside, 0% uncertainty).
How RAU is calculated: RAU divides upside potential by forecast uncertainty (RAU = Upside % ÷ Uncertainty %). A RAU of 46.3 means the upside is 46.3× greater than the uncertainty-making it a high-confidence growth opportunity. Target RAU ≥2.0 for balanced risk-reward.
Risk-Adjusted Upside by Player

Roster Pressure Index (RPI)
Squad depth pressure based on Z-score distribution. Negative RPI = thin depth, positive = deep roster.
What This Shows
Z-Score explained: Measures how many standard deviations a player's strength is from the position average. Z-Score = 0 means average, +1.0 is one standard deviation above average, -1.0 is below average.
How to use: RPI < -1.0 indicates critical depth shortage. These positions need immediate reinforcement. RPI > +1.0 suggests strong depth, allowing selective, high-value additions only.
Current market: young midfielder position shows weak depth (avg Z-score: -0.00). RPI: -0.00.

Lowest Z-Scores
Age-Share Concentration (ASC)
Identifies players capturing disproportionate value relative to age group representation. Positive ASC = value concentration.
Understanding Age-Share Concentration (ASC)
FC Arouca's Mateo Flores in the 21-23 age bracket has the highest Age-Share Concentration at +-43.3%. That means Gorby captures 51.2% of total market value while representing only 94.4% of players in their age group-showing dominant elite status.
In second is FC Famalicão's Mathias de Amorim with a +-43.3% ASC (51.2% value share vs 94.4% player share in 21-23 bracket). Third is Marcos Peña of FC Famalicão with a +-43.3% ASC (51.2% value vs 94.4% players in 21-23 bracket).
How ASC is calculated: ASC = (% of total value) - (% of total players) in age bracket. A +-43.3% ASC means the player captures -43.3% more market value than their numerical representation-indicating marquee status. ASC > +15% = elite dominance, ASC < -15% = potential value targets.
Value Concentration by Player

Our database tracks 18 Liga Portugal Young Midfielders with comprehensive market valuations updated for the 2022-23 season.
How are Liga Portugal Young Midfielders ranked?
Liga Portugal Young Midfielders are ranked by our proprietary Analytical Strength Index, which is specifically calibrated for Young Midfielders. The score combines six factors: Historical Achievement Index (35%) measuring peak career value, Current Performance Proxy (30%) reflecting recent market signals, Playing Time Utilization (18%) tracking minutes played, Age-Adjusted Performance Curve (12%) using position-specific peak ages, League Quality Coefficient (3%) for Liga Portugal competition level, and Club Tier Multiplier (2%) accounting for club prestige. This methodology is grounded in academic research including work by Dendir (2016) on age-performance curves and Franck & Nüesch (2012) on hedonic pricing models.
What age do Young Midfielders peak?
Midfielders typically peak at age 26-27, with a decline rate of 6.0% per year after peak. Central midfielders require a blend of physicality, technical skill, and tactical awareness. The optimal playing time for peak performance is around 2,400-2,500 minutes per season.
How much does it cost to sign a top young midfielder from the Liga Portugal?
Transfer fees for Liga Portugal Young Midfielders vary significantly based on market value, contract length, and club bargaining position. For the top-ranked young midfielder Victor Froholdt (market value: €30.0M), estimated transfer fees would range from €24.0M to €42.0M depending on contract situation. Players with longer contracts (3+ years) command premium fees (1.2-1.4× market value), while those in the final year may be available for 0.8-1.1× market value. Our fee estimates are derived from historical transfer patterns and contract-clock modifiers validated against actual Liga Portugal transactions.
What is the value forecast for Liga Portugal Young Midfielders?
Our 1-year forecast model projects market value changes for Liga Portugal Young Midfielders based on age-curve depreciation, historical trajectory, and playing time adjustments. The forecast combines three factors: age-based appreciation/depreciation (pre-peak players gain ~5% per year toward peak age, post-peak players decline at position-specific rates), market trajectory momentum (comparing current to peak value), and playing time confidence (regular starters receive +2% boost). Forecast confidence intervals account for position-specific volatility-midfielders have ±12-15% volatility. Young players (under 22) and older players (over 32) receive 1.15× uncertainty multipliers due to unpredictable development or decline patterns.
