I would say there is never right or wrong in investment.
If one has lesser risk appetite, then settle for a 5-8% return rate, which invest in big cap or bond area, then it is "right" for him/her
If one has higher risk appetite, then want to chase for 20-30%, then opt to invest in second liners, smallcap or whatever riskier asset, then it is "right" for him/her also.
We cannot say the 20-30% potential gain asset is better than 8% one, as the risk associated with is different to start with.
Just invest suit to individual risk appetite and preference. Investment is never a 1+1=2. There are plenty of unforseen circumstance or some risk we never expect nor foresight, as future is never known.
We always welcomed any taught/opinion, which is beneficiary to all which open out our mind, view regarding the investment field.
The more we know how others invest, the more better we equip ourself.
Some experience investors may totally dislike glc, which is understandable. (Just need to look through the historical performance of GLCs stock, then explain it all)
Some experience investors may not prefer smallcap, which is understandable. (Look back second board counter history as well as Mesdaq)
Some may opt to his/her own liking stocks, which is understandable (because over the decade, they consistently give good dividend, and improving)
Having said that, surely not all counters as above mentioned perform the same or has poor performance one, as there is never a generalising case.
But there is nothing wrong with their personal experience and opinion.
Everyone come out with opinion has their own reason, and experience associated with it.
The most important is to look why others have such an opinion. One not necessary agree with the opinion, but look through why there is such opinoin arise is always good and beneficiary in term of future decision making, and serve as own reminder.
