You can do both, not an either or, but focus on the one you like the most
RE and CRE are great if done carefully and methodically and with patience, but so is picking individual stocks.
I love researching good companies with good growth prospects and a long horizon to allow for compounding of value, much like finding a good property in a good area with good long term demographics in a friendly regulatory environment etc to allow for capital appreciation.
EG. I have been buying a small pharma company in the opthalmic space, Harrow, HROW since May at $10, with good growth prospects and in an area with long horizon of medical need for the diseases it treats, they keep announcing better earnings each quarter, and stock now $44 in just 3-4 months, I've bought other companies with good products in the past like NVidia back in 2009 as they made the best graphics chip, G-Force, for gaming. I've also had to sell some stocks that went no where or declined when their "great" product turned out to not be so great, like buying a good property to see the neighborhood change over the years.
Which is better? well that depends on you and your knowledge and your skill/luck etc and no one else.
with stocks and with RE, sometimes you get the turn-around projects too, which can suck up your money and be losers or end up as huge winners, when the community recognizes the value add or the company turns it around. This month I am buying heavily into a tech company that the street hates and is dumping for fears of an accounting scandal. So, a risky reclamation project, like many shopping centers bought in potentially gentrifying neighborhoods.
Academic studies both in Europe and US, show the average RE investor underperforms the public equity REITs by 3.5 to 4% per annum, but that's average, and that equity REITs have outperformed the SP500 by 2% over last 50/40/20 years (NAREIT data c1974 onwards) but not in the last 15 yrs, when SP500 has 15.1% annual return since 3/9/09 and has beaten most asset classes. longer term SP500 return is 8.4% nominal and 6.9% Real since 1801.
you can do both, but focus your time on the one you love the most if you have a preference as each stock or property requires 50-100 hours of research time typically before pulling the trigger for me,
best of luck Kyle
