Note that people that time the market or people that are suppose to time the market are those investors that haven't gone far in there accumulation so they will want a Dip to take advantage and increase there portfolio.
You are wrong to think that those that has not gone far in their accumulation journey need to time the market, why they are even the ones that shouldn't time the market but rather to be buying regularly, persistently without any form of timing the market, a low coiner shouldn't be encouraged to be timing the market to buy the dip in form of taken advantage because it can difficult to have a desire dip. But however, buying the dip should only be seen as a secondary accumulation strategy such that an investor can have an ongoing Dcaing and if possible make provisions to buy the dip with a reserve funds. Why those that has gone far in their accumulation journey can decide to adopt the timing strategy of not buying in the same frequency they were buying when they were low, that is to say the reverse of your statement should be the case study.
You should take note that as an newly investors who is just starting the accumulation journey or have limited experience should focus on consistency and regular investment regardless the market downturn, rather than trying to time the market this approach helps to reduce the impact of market volatility and timing risk management.
Why new investor to avoid timing the market, lack of experience can be a cause as an new investor you may not have the experience knowledge to accurately time the market, and trying to time the market can lead to emotional decisions making which usually leads to impulsive and costly decisions mistake.
