The PokéViews Portfolio Backtester lets you build a hypothetical portfolio of Pokémon cards, sealed products, and graded cards to see how it would have performed over time using real historical price data. Select a start date, choose your holdings, and compare your results against market benchmarks like the Sealed Index, Graded Index, PV100, or PV250.

Backtesting lets you test collecting and investment strategies before committing real money. You can evaluate whether sealed products outperformed singles over a given period, see how a concentrated portfolio of chase cards compared to a diversified mix, and measure whether your picks could have beaten the broader market. It turns hindsight into a tool for making more informed decisions going forward.

The backtester uses historical PriceCharting market price data to simulate portfolio performance. The methodology is as follows:

Start Date: You choose a month when you would have hypothetically purchased your holdings. Prices are set using the actual market prices from that date.

Holdings: You can add up to 50 unique items — raw cards, graded cards (PSA 10), or sealed products — each with a custom quantity.

Valuation: Your portfolio is valued daily from the start date to the present using historical price data for each holding.

Benchmark Comparison: You can optionally compare your portfolio's performance against one of four PokéViews market indices (Sealed, Graded, PV100, PV250).

Returns: Total return, annualized return, and benchmark-relative performance are calculated from the simulated daily valuations.

All prices are sourced from PriceCharting market price data, updated daily. The backtester uses the same historical price series that powers all PokéViews indices and charts. For raw cards, the ungraded market price is used. For graded cards, the PSA 10 price is used. For sealed products, the sealed market price is used. Prices are denominated in USD.

Four benchmarks are available for comparison. The Sealed Index tracks the performance of sealed Pokémon TCG products. The Graded Index tracks PSA 10 graded card prices. The PV100 and PV250 track the top 100 and top 250 most valuable English Pokémon cards respectively. PV100 and PV250 require a start date of April 2024 or later, as that is when those indices began. You can also select no benchmark to view your portfolio in isolation.

Chart Indicators Reference

Indicator	Description	How to Interpret
Bands	Bollinger Bands are volatility bands placed above and below a moving average. They widen when volatility increases and narrow when volatility decreases.	In traditional finance, price touching the upper band may suggest overbought conditions while the lower band may suggest oversold conditions. Bands squeezing together often precede increased volatility or a breakout.
EMA-30	An Exponential Moving Average (EMA) is a type of moving average that gives more weight to recent prices, making it more responsive to new information than a simple moving average.	Price above EMA-30 suggests short-term upward momentum; below suggests downward momentum. Can act as dynamic support or resistance.
EMA-90	The 90-day EMA smooths medium-term price movements while remaining more responsive to recent changes than a simple moving average of the same period.	Shows medium-term trend direction. Useful for identifying support and resistance levels. Price crossing above or below can signal trend changes.
MA-200	A Simple Moving Average (MA) calculates the average price over a specified period. The 200-day MA is one of the most widely-watched long-term trend indicators.	Price above MA-200 is generally considered bullish; below is bearish. Often acts as strong support in uptrends or resistance in downtrends.
RSI	The Relative Strength Index (RSI) is a momentum oscillator that measures the speed and magnitude of recent price changes on a scale of 0-100.	Rising RSI values indicate strengthening momentum, while falling values suggest momentum is slowing. Changes in RSI direction can signal when a trend may be changing. The 50 level serves as a neutral reference point.
