Advice if i should continue holding my stocks for more growth or sell to take profits? I do not need $$ at the moment. Also should i continue buying stocks of ETF with my salary?

If old liao convert to ETF except money u really dont mind going to 0.

If you don't really need the $$ and believe that the stocks will keep going higher, I would continue to hold.

Start with the end goal in mind. If this is for retirement, stay invested and only convert to lower risk instruments during your drawdown years. As per the individual stocks wise, there are plenty of factors to consider - macroeconomic environment, stock financials, stock management direction, competition etc. If you want to start having more clarity on either I can set aside some time to sit down and run through it with you. The vagueness of the situation described above will not lead you to an answer you seek IMHO.

Continue to invest. if there is profit and you are not sure whether profit will be cut, no harm taking some profit off and put them in better investment (if you have one). otherwise, if the stocks you bought are atable and good, long term investment is a good strategy too.
