if market sentiment goes high LMF(40M) can move faster than EXPO(1.59BN) according to the share volume...
Also LMF's Annualized EPS may be Rs 35.00+ so according to market PE this share is still undervalued. LMF if price go high there is more chance for share splitting in future to increase the share volume for better liquidity.
So in my opinion it’s good to keep both the shares in your portfolio MT to LT. Not a BHS recommendation. Do your own research before you buy, sell or hold.
