Growth of your money
Log scale is on by default — over decades it's the only honest way to show compounding, because equal percentage moves get equal vertical distance.

What this is
Every trading day splits into two separate windows, and a stock's return is the product of the two:
- Open → close — the regular session, while the market is open.
- Close → next open — the overnight gap, while the market is shut.
Chain those two together and you get buy-and-hold exactly. So this page splits any stock's history into the part earned during the day and the part earned overnight. For a lot of big US stocks the result is lopsided in a way most people don't expect.
Each strategy assumes you start with your chosen capital and reinvest the entire balance every single day. Returns compound: two consecutive +10% days turn $10,000 into $12,100, which is +21%, not +20%.
Set a buy and sell fee to see what brokerage does to all this. Both daily strategies pay a fee twice a day, every day; buy & hold pays once at each end. Over a long history that gap is the whole story.
Not financial advice, and not a tradeable strategy. These numbers ignore commissions, bid-ask spreads, slippage and tax — and you cannot actually transact at the official opening and closing prices. Prices are adjusted for splits and dividends. Data from Yahoo Finance; it can be wrong.
