Should I pause my SIP when the market falls?The numbers say no. On identical money in and the same exit, the investor who kept buying through a 40 percent fall ended with 329 more units and Rs 39,471 more than the one who paused and bought back at full price.

Pick a quarterly window before you buy. [Read the note: Your portfolio is not down. You are looking too often.](/blog/2026-08-06-morning-checking-too-often/) Does a stop loss cap my loss?No. A stop is a trigger plus whatever fill exists.
