Wow, the comments here are certainly entertaining. I love it how people's emotional attachments to real estate reallys come out.
When I was building my client base years ago as a stock broker and futures trader i met some people who were in one camp or the other, real estate or the stock market. It was black and white. never, not once, did i meet someone who diversified and did both.
Firstly, I would make the argument that you really cannot compare the two as most people do, which is in terms of risk and reward, because their fundamental structures are entirely different. Taking a look at some of the most glaring inaccuracies i've read:
You can't buy stock with no money. yes, you can. it's called the carry trade but only the wealthiest can play that game, and then return aren't spectacular
You can't repeat that 10 more times buying stock for no money. see cary trade
You can't buy $600,000 worth of stock for $4,500. you can't do that in any business. you can CONTROL $600,000 worth or RE for $4,500...and yes, with $4,500 you can control a huge amount of stock thanks to options, futures, and options on futures. in fact, $1,000 gives me control of 42,000 gallons of crude oil.
You can't buy $330,000 of stock for $30,000 and have a monthly dividend of $2,050. again, yes you can...but the stock's dividend would have to be so outrageously high that it would be fundamentally unstable, and not work in the long run. so here, RE is the clear winner.
There are dozens of others, but this is getting a little long.
One massive difference between these two business models is something that only @Jeremy T. brought up...liquidity. and with liquidity comes speeds. the stock and futures market is the fastest way to build wealth, no question about it. Anyone heard of high frequency trading? these guys make millions each day trading in the milliseconds.
However, with liquidity and speed comes a massive edge real estate has over stocks in that only with real estate is there a chance of finding a smoking deal no one has discovered yet.
Plus, with real estate you have a lot more control over all aspects of your business. for the most part, it's just managing risk/reward ratios when it comes to stocks since it's entirely about speculation. there's no screening of tenants with stocks, nor is there the ability to negotiate...both of which RE allows for.
In the end, to say that one is better than the other because of "X" is just plain lunacy. I know people who make a living playing poker. they say it's better than any other investment out there. do you think it is? I don't, but i am in no position to answer having never played it for real money.
But there's one massive major advantage stock and futures trading has over everything else (all businesses and investments): you can make money when the market is going down.
Nowhere in real estate can you say to someone, "i will sell you this property today for $750,000 (which i don't even own), and i'll buy it back at some point in the future once prices fall."
Selling something you don't even own and profiting from the investment's decline in value is something only stock, options and futures traders can do. Lots of people made a killing in 2007 - 2009 when real estate and the stock market were crashing. were they invested in real estate? no. they were shorting the banks, lending institutions, builders, REITs, etc. in essence, they were traders.
of course with this massive power comes massive risk. after all, in theory your losses are unlimited. at least with real estate the most you can lose is your initial investment.
last but perhaps most important is real estate's trump card, scarcity. As Lex Luthor put it so well in Superman, "it's the one thing they aren't making any more of."
So as you can see, each investment or business has its advantages and disadvantages.
in short, you cannot compare real estate vs. stock trading/investing. there are far too many vastly different independent variables. Better to find what you are better at and/or what you enjoy more and what suits your personality.
Do you need complete control or the need to physically "own" something? do real estate
Are you more statistically inclined? do stock and futures trading
Can you leave you money parked somewhere for a few months/years? do real estate
Do you need the biggest bang for your buck regardless of risk? try roulette :)
