Do you guys find any use of the price calculators? Eg this
Disclaimer
If I've understood correctly, they calculate the fair mathematical price for options based on "random walk" price of stock and interest rate and volatility. I tried this calculator with couple of calls and puts and it gave me almost exact the same prices as which they are traded. So what do I get from this?
There's a hell of a lot of computers in the options market trading based on those Black-Scholes pricing model calculations.
If you're trading based on a sound understanding of fundamentals, you can therefore consistently make money off of the computers.
I've been extremely conservative: selling cash-secured puts on TSLA. There was a price where I figured (a) TSLA wouldn't drop below that, and (b) if it did, I sure wanted to buy for the long term.
During 2014, none of my puts were exercised. It was basically like earning 12% interest -- a very good deal. Better than owning the actual stock was during 2014.
Now, why did I have this opportunity? A combination of two things: a whole lot of people who think TSLA will crash (and therefore willing to buy protective puts at low prices), and computers using mindless Black-Scholes valuation for the options. Most of the people in the market knew nothing about TSLA, had never done their research, so I got an advantage by knowing more.

@matias, are you thinking about writing (selling) or buying these puts? Either way, I'm not interested (though you might be):
Writing: probably a safe bet, but it ties up a huge amount of cash or margin, $15,000 per contract. I do all my options trades in my retirement account, which prohibits use of margin, and I don't like to keep that much cash in non-interest-bearing accounts. That said, it's not a bad return on that cash: assuming you hold to expiry and the put is still OTM, you get $10.46 return on $150 of cash/margin "invested", or about 8.4% annualized rate of return, while taking on the risk of having TSLA put to you at $150.
This, more or less (different strike prices, various durations), is what I made my money on in 2014. For some reason I suspected that TSLA might not go up and stay up during 2014, but I knew it was very unlikely to sink a lot. This bet was correct as it turned out.
The key point if you're writing puts at $150 is that you have to think that TSLA's a good buy at $150, even if some bad news has come out (because some bad news would have to have come out in order for the price to drop to $150). If that's what you believe, then you win either way; if TSLA drops, you will buy it on the drop without even having to look at the stock market.
(For me this was a particular advantage because I knew there would be long periods in 2014 when I wouldn't be able to follow the market closely.)
