HISTORICAL BACKTEST · AAPL DAILY
What this backtest found
2016-09-28 to 2026-09-25 · $10,000.00 USD starting capital · costs as specified below
The strategy returned 24.81% over the full test period, compared with 1097.22% for buy and hold. It underperformed that benchmark on total return. Its largest decline from a previous equity high was 24.23%.
CAGR is the equivalent compounded yearly return across these dates, not the return earned in every year. Drawdown measures the largest fall from a previous daily equity high. Ending equity includes any open position marked to the final close.
How this strategy works
AAPL is tested on daily bars with one long position at a time. Entry conditions are combined using AND: every condition must match. A close signal executes at the next session’s open.
- Entry: RSI(14) below 30.
- Indicator exit: RSI(14) above 50. It executes at the next open.
RSI: Wilder’s smoothed average gains and losses produce an oscillator from 0 to 100. Each RSI period and threshold comes from the rules above. “Below 30” tests the current reading; “crosses above 30” requires a move from 30 or below to above 30. RSI can remain near extreme readings for extended periods; a threshold does not guarantee a reversal.
5% fixed stop: measured from the raw entry open, before execution slippage and fees. Opening gaps fill at open; otherwise daily high/low touches determine fills. A stop takes priority when both stop and target touch in one daily bar.
Holding limit: queue an exit after 20 invested sessions and execute at the next available open. Entry and exit sessions count toward the displayed holding period.
Strategy versus buy and hold
Both curves start with $10,000.00 USD and use the same historical dates. Buy and hold returned 1097.22% (28.21% annualized), with 38.73% maximum drawdown.

Annual returns use the previous year’s final equity, or initial capital for the first year. Ongoing drawdown retains the previous all-time peak, including peaks in earlier years.
Execution risk observed in this test
A 5% stop did not cap every loss: the trade exiting on 2020-03-16 lost 5.99% after opening beyond the stop. Daily gaps can bypass the intended exit level.
What these results mean
The strategy’s 2.24% annualized return was 25.97 percentage points below the long buy-and-hold benchmark’s 28.21%. Its worst daily peak-to-trough decline was smaller by 14.5 percentage points. That is a return/drawdown trade-off, not proof of better risk-adjusted performance. It held a position during 8.16% of sessions; cash earned no interest in this simulation.
Across 20 closed trades, 55% were profitable. The average winner was 6.62% and the average loser was -5.17%. Profit factor was 1.55: $1.55 of positive closed-trade P&L for each $1 of losses. The longest losing run was 4 trades. Win rate alone does not capture the size of wins and losses.
The weakest displayed calendar period was 2018 at -13.87%. First and last years may be partial. A full-period average can hide substantial variation.
The longest observed drawdown lasted 1791 calendar days, with 1231 underwater sessions, from 2020-03-04 to 2025-01-28. Equity regained the earlier peak on the ending date.
Best closed trade: 16.44% · 2025-04-07 to 2025-04-25, exiting because of indicator exit.
Worst closed trade: -5.99% · 2020-02-28 to 2020-03-16, exiting because of gap below stop.
Fees and slippage are 0% and 0% per side. This is a zero-cost simulation; adding execution costs can reduce results. This report contains no out-of-sample validation or parameter robustness study, so it does not establish that these rules generalize.

Exact rules and methodology
Read the strategy-specific explanation above.
- Signals use completed daily bars; entries and indicator/holding exits execute at the next session open. Indicators warm up using earlier history; no pre-range entry signal is carried in.
- Opening stop/target gaps execute at open. Otherwise a scheduled indicator/holding exit executes at open; within a bar, stop takes priority if both stop and target touch.
- Initial capital $10,000.00 USD; one fully allocated fractional position, no pyramiding or leverage. Fees and adverse slippage apply to entry and exit. Buy-and-hold benchmark is always long.
- Open positions are marked at the last close without an assumed final sale fee. Cash interest and dividends are excluded.
Results are calculated on the supplied daily prices. Dividends and cash interest are excluded.
Calculated: 2026-10-01 17:26:53 UTC. Engine: 3.1. Data: AAPL, 2016-09-28–2026-09-25.

Understand the metrics
What is CAGR?
The equivalent compounded yearly growth across the test’s elapsed calendar dates. It is not the return earned in each year.
What are drawdown and drawdown duration?
Drawdown is the percentage decline from a previous daily equity peak. Longest drawdown duration is the longest observed calendar time from a peak until that equity level is regained, or until the test ends. Underwater sessions count daily closes below the peak and exclude the recovery close. This duration need not belong to the deepest drawdown. “Unrecovered at test end” means the recovery date is unknown.
How is profit factor calculated?
Gross positive dollar profit divided by the absolute sum of negative dollar profit across closed trades, after configured costs. It excludes open positions. Because capital compounds, later trades can have greater dollar weight. Legacy reports without saved dollar P&L use reconstructed amounts from rounded trade returns and are labeled approximate. No losses gives “No losing trades,” not a finite ratio.
What are best/worst trade and losing streak?
Best and worst rank closed trades by percentage return. Longest losing streak counts consecutive closed trades with negative returns; a zero-return or positive trade breaks the streak. These statistics do not forecast future outcomes.
How are holding period and time invested measured?
Holding periods count sessions inclusively, including entry and exit sessions. Time invested is the share of sessions with a position at any point; it does not measure intraday hours. Average winners and losers use closed-trade percentage returns.
