Past returns don't repeat. What does the price assume now?

These tables show what already happened. A buyer today gets the next ten years, and the price already reflects what the market expects. The reverse DCF calculator shows the growth today's price implies, so you can judge whether it is realistic.

Is it a good idea to time purchases by month?

Usually not. Each month has only about 22 observations here, one big year can swing an average, and the gaps between months are small next to a single year's range. Seasonality is a curiosity, not a trading signal.

How are the monthly returns calculated?

Each month's return runs from the previous month-end close to that month's close, using prices adjusted for splits and dividends. The current, unfinished month is left out.
