Absolutely not. Most of the investors are regular people who need the money for their retirement. They sell stock when they need the money to live.

Stop thinking that investment is like in the movies where everyone watches their portfolio value 24/7, please.

So you're asserting that now is good value, relative to when you're 65. That's timing.

Not at all. Buying and selling on a fixed schedule regardless of the price of the asset is absolutely not timing.

Let me take the Investopedia definition[1]: "Market timing is the act of moving investment money in or out of a financial market—or switching funds between asset classes—based on predictive methods. Market timing is the opposite of a buy-and-hold strategy, where investors buy securities and hold them for a long period, regardless of market volatility." (emphasis mine)
