Flashback is a new member of the Stockfuse family. It is a simple app that lets you backtest trading strategies. Enter a few positions and hit “Run,” Flashback crunches the numbers and provides detailed historical return and risk analytics, allowing you to make more informed investment decisions.
Flashback allows you to enter quantity either in number of shares or as percentage of overall portfolio. In the “shares” mode, entering “20” indicates you’d like to hold 20 shares of a stock. In the “percent” mode, entering “20” means the position has a weight of 20% in your backtest portfolio.
Cash is automatically added. For example, if the weights of your positions (in percent mode) add up to 80%, we’ll automatically add a 20% cash position. If the weights add up to 120%, we’ll include a -20% cash position (i.e., we assume the portfolio is 1.2x levered).
Flashback always reports total returns, which includes dividend reinvestments and other corporate actions. By contrast, the percentage returns provided by Yahoo and Google are price returns only and understates actual investment performance.
Yes, when entering your position, type
. (period) to see a list of supported total return indices. Our researchers have compiled a number of long-term indices specifically for Flashback:
.ACTR: A total return index measuring the performance of the US stock market, including all shares traded on NYSE and NASDAQ.
.TSY: A total return index measuring the performance of the US Treasury (government bond) market.
.TIPS: A total return index measuring the performance of US TIPS (Treasury Inflation-Protected Securities). This includes simulated returns calculated by our researchers before 1997.
.CORP: A total return index measuring the performance of the corporate bond market.
.DWTR: A total return index measuring the performance of developed world stock market (returns are in USD).
Portfolios are only rebalanced if 1) there are no short positions and 2) quantities are entered as percentages. If both conditions are met, positions are rebalanced monthly.
We assume that your return is -100% (i.e., complete loss of capital) and no further returns will be calculated thereafter.
