There is an interesting write up on the health care sector at SGX My Gateway.
Quote below is the last paragraph of the write up:
" Of the stocks tabled above, 13 currently maintain Price-to-Earnings (P/E) ratios, with an average P/E of 31x and median P/E of 25x. The five year average P/E for 10 of the stocks is 29x with a median P/E of 23x. P/E ratios and history for the respective stocks can be found in SGX StockFacts (click here)."
... end quote ..
From above it can be seen that ISEC has a lower valuation with a trailing P/E of 22.7 times.
As a side note - ISEC has no debt and a cash horde of S$21.1 mil. This put ISEC in a position for further acquisition/jvs.
