What we should do is to identify one or few Trojan Horses and start accumulate it in a silent manner. How can you spot these stocks. Best is to look at the operating cash flows rather than PAT or revenue because those can be manipulated with accounting entries.
In a simple form if a company able to balance their trade receivables with trade payable their net cash flow from operations should be higher than their PBT because BPT is after depreciation and amortization entries which are not coming into cash flows. Then if you happened to find such a stock and next check with their trend, upward or downward. If it is upward then that will be your Trojan Horse. Then study the price to decide on entering point.
Lets see how many Trojan Horses can be found in CSE.
