For trading in Future/Options
Always trade with that much quantity which does not disturb your sleep.
When trade size gets out of hand and too large, all the analysis in the world is worthless.
Percent risk you’re willing to accept per trade –We recommend less than 2%.
Capital 20 lakhs
Available for margin: 7 lakhs (1/3rd of total capital)
We can build positions for about 7 lots in Nifty futures
IF nifty moves 1 point against your favor then you can lose 75*7 = 525 rupees.
If NIFTY is at 11200 then Exposure = 60 Lakhs (7*11200*75)
Risk per position = 60,00,000 * 1% = 60,000/-
So if you can afford to lose Rupees 60,000 in a single trade then your trade size should be 7 lots.
Suppose you can afford to lose only rupees 20,000 in a single trade then your lot size should be 2 lots.
If NIFTY is at 11200 then Exposure = 17 Lakhs (2*11200*75)
Risk per position = 17,00,000 * 1% = 17,000/-
For trading in Equity
Positional Traders are generally concerned with short term investing. So most favored strategy to use is allocating a specific amount of capital to each trade. The amount is determined by the trader based on account size and how diversified they wish to be.
Assume a 1,00,000 investment account. The investor decides they will only take up to 5,000 in any stock trade they make. The investor can therefore buy 20 stocks, investing 5,000 in each.
A more conservative investor, wishing to be more diversified, may buy 40 stocks, only investing 2,500 in each.
Given this scenario, assume our investor wants to invest 2,500 in RELIANCE. The current share price is 1,360. Divide the desired investment amount by the share price to get the position size: 2,500 / 1,360 = 2 shares.
A not-so-conservative investor may decide to invest 20,000 in each stock, and only take five positions. For such a non-diversified portfolio, a stop loss strategy is recommended, as discussed above (For Future/Option trading).
The Capital Allocation method is mostly used by passive investors, because it is an easy and efficient way to allocate capital.
With this method it is best to invest a small portion of the total account in each stock, achieving some level of diversification. That way, if some stocks go down, hopefully some of the others will rise, offsetting the loss.
A stop loss can also be utilized with this method to control risk within each trade. When buying 2,500 worth of stock, the trader may not wish to risk all that capital should the company fail. A stop loss can therefore be placed below the entry price to close out of the position if a loss becomes too large.
If an investor has a lot of positions they may choose to simply close out a position if the stock declines by 15%. Therefore, a stop loss order is placed 15% below the entry price. If the stock declines 15%, the trade is closed out and the trader preserves 85% of the capital allocated to that stock.
