In regards to DCA, here is my TLDR personal summary.

Funds/ETFs - Yes.
Gold - Situational Yes.
Stocks - Generally No.
Crypto - Hahahahaha

Yes, that is what Buffet said. But majority of people aren't Buffet.
The keyword here is....which stocks?

This is purely personal opinion. I need to open with this.

DCA works for securities & commodities which represent a high probability store of future value. Things that you can be almost sure that will appreciate in value.
What are these? Funds, ETFs and anything which tracks an index are very likely to go up hence DCA works here. Gold too, over time.

For stocks I put a 'generally no' and the reason is most business do not stand the test of time well. In 10 years, more businesses will get replaced with other businesses as compared to businesses that will grow bigger. See the S&P500 companies, the rate of companies getting replaced in the index has nearly doubled in the past 10 years as compared to the 1960s. There is more risk, more unknowns. If you are telling me that you have spotted a business that is absolutely bang-on to multiply it's size in 10 years and you are willing to bet your house on it, then by all means DCA. Because that stock now is seen as a higly trustable store of future value. Even the hedge fund billionaires admit the difficulty of spotting such companies in recent times. I'm not saying you can't, I'm saying I admit to my own weaknesses that I most probably can't. Statistics are against me too. Keep in mind for every Coca-Cola; there is a Polaroid, Blockbuster and Yahoo. Stocks for me as a smaller investor, is something that I need to monitor constantly amid macro forces and adjust.

I wanted to explain is as brief a text as possible, and this is about the best that I can manage. I hope that clarifies my position.

I do have some basis for what I say. I first started investing in unit trusts about 16 to 17 years ago. Stock investment came later for me. So, I have done the comparison.

But nothing beats actual experience. If you have the budget, you can give it a try. Use RM12K to DCA for 12 months into a reputable unit trust with FSM One Malaysia and use another RM12K to DCA 12 months into Top Glove, Tenaga, Public Bank or whatever stock that you fancy. Please compare the results after 12 months. 

Here is a very simplified line for hyperinflation.

Hold assets, not cash.

Unfortunate to see Penang's potential investments get tanked by the one and only Azmin Ali.
