Why do you call these smaller "jewels," "low risk and high potential return?" Aren't smaller stocks usually riskier?

For many years smaller cap Thai stocks performed rather well. They were under-priced, under-followed and mostly ignored by the institutions and brokers alike.  The individual investor with some know how and experience could beat the SET index, as I here did for many years.  But from 2017 on this started to change...individual retails investors started abandoning Thai stocks as a savings vehicle, while punters and speculators, index funds and so called trigger funds increasingly took over.  Not least, the controversial derivative warrants  (DW) market.  As here amply pointed out back then: individual investors at present make up barely 40% of total SET volume vs. some 60-70% in years past, but this has increased of late with individuals coming back. 

The result is, smaller cap stocks have been in the doldrums for some time, many dropping 50% or more and the MAI index graph looks like its " going to hell in a hand basked".  To be fair many reported disappointing earnings and so their p/e ratio's became overstretched, this is one reason not to turn over positive on the sector, just yet.   Further, its becoming increasingly difficult to get any added value research information by any means, as most as these companies have been put on alert by the SET/SEC to be ultra careful in disclosure.  Hence company responsible visits with management have become less interesting, not least due to Covit-19.  In early April 2020, I went max. bullish for the first time in many years, stated so at my front page back then, and smaller and mid cap stocks have largely outperformed again since.  (January 2 2022).
