Strategy: Selling Put Options: The Best Income Method?

I understand, but I was thinking of realtime monitoring the position and close it immediately if the credit minus the costs has been eaten up by the drop.
By this the 20% drop of the acct could be prevented IMO, at least under normal circuimstances...
Do you realize that if you sell option & buy it back immediately you are already losing money?

Yes, the spread effect between Bid and Ask...
But let's be realistic, in this case that won't happen because of the calculated-in cushion (stop-level) into the strategy, agreed?
 
Sorry, there was a typo in the calculation ($490 vs. $49). Here's the fixed version:

Applying the same strategy, but now using a strike that is 10% off of the current spot and using current quotes gives that yield:
Code:
INTC

29.00    1.26    -0.03    1.28    1.35    17    8029
30.00    1.73    +0.03    1.76    1.82    30    1152
...

Code:
cur_spot = 29.59
days     = 81 (= 2.7 months)
strike   = 26 (about 10% lower than the current spot)
mid_put  = (0.47 + 0.51) / 2 = 0.49
credit1  = mid_put = 0.49
profit_potential_normal         = 0.49 / 26 * 100 = 1.8846%
profit_potential_with_5x_margin = 5 * 1.8846 = 9.42%

Now we have a big cushion of 10% before the stop can hit.

The total credit is of course: 0.49 * 100 = $49 for each contract.

When using just 1 contract the capital bound is: 26 * 100 = $2600,
of which only 1/5 ($520) is our own money, and the rest ($2080) is margin.

The profit is fix 9.42% in 2.7 months (annualized 49.2%) as long as the stock doesn't fall more than 10%.
(IMHO very unrealistic that INTC falls more than 10%)

Btw, in this analysis the "right entry time" has not been analysed, ie. FA & TA, as well ex-dividend dates etc.
The Call quotes are of course not needed here, it's just for the archive...

Now, this I would classify as a "safe investment".

PS: "mid_put" of course indicates that we are using a limit order in between the Bid and Ask spread, not market order...

The beauty of this strategy is also:
- one does just 1 trade in 2.7 months... ;-) (maximally 2 trades if the stop gets hit).
- to get stopped-out is very unrealistic because of the big cushion of 10% calculated-in.
- a fix profit of 9.42% in 2.7 months (annualized 49.2%) as long as the stock doesn't fall more than 10%.
- the profit (ie. the credit) is received immediately when opening the position.
(but this is of course the "unrealised profit" up-front; only after the expiration date it becomes "realised profit").
- the own account (excluding the credit) is protected by the 10% stop level, ie. is risk-free under normal market conditions.
- ...

Of course in reality one would do many such trades with different stocks in parallel to apply diversification.

PS: the annualised profit has to be reduced by the interest paid for the margin. For example at the broker IB the interest paid for margin is 1.87% p.a.
That means we have to subtract that from the 49.2% above, giving us a net annualised profit of 47.33%.

Do you realize that you don't have any cushion or bid/ask spread wouldn't be an issue.
 
Come on guys, admit that this is indeed a brilliant strategy,
even if it is just a conservative investment strategy without any "action" like in daytrading ;-)

I like especially the maths behind it: everything can be pre-calculated before opening the trade and can clearly be verifed by everyone.

I have not provided yet some probability computations, but that will follow soon...
