During the times when stock markets are packed with volatility, it becomes most important how prudently an investor picks his stocks. A wise bet during dips can help him not only in building a strong portfolio, but also save his hard earned money from getting burnt in the stock market turmoil. \u201cStock picking is more important than ever now, told N Jayakumar of Prime Securities to ET Now. Aviation, infra, NCLT space as well as NBFCs are some of the themes where an investor can do stock picking at the moment, advises N Jayakumar. IT and pharma stocks are also good bet, he adds. However, NBFC stocks may come under pressure due to higher interest rates ahead, he tells ET Now. Due to the ongoing turmoil in the heavyweights at Sensex and Nifty currently, midcap stocks have returned into contention, he says. However, he advises investors to be cautious while making investments in the dips at present. \u201cInvestors should go to professional money managers when approaching midcaps,\u201d he advises. Sensex and Nifty have been under immense pressure in the last three days witnessing steep correction on the base of global sell-off and worries hovering over long term capital gains (LTCG) being taxed on equities, as the budget 2018 proposed. Yesterday, global brokerage Jonathan Garner of Morgan Stanley told CNBC TV18 that those counting on this ongoing global sell-off as an opportunity to make portfolio richer with ace stocks need to be cautious a bit. \u201cDon\u2019t think this market dip needs to be bought aggressively; will be cautious on equity markets; would not go to buy in a hurry,\u201d Jonathan Garner of Morgan Stanley told CNBC TV18. Projecting a target of 35,700 for BSESensex by FY18 end, Morgan Stanley is overweight on India against China \u00a0and prefers to buy Indian equities. Before beginning to buy on dips in stock markets, investors must wait for the US dollar to become more weak, Morgan Stanley told CNBC TV18. The markets have seen their value eroded in the last few days on the global fears of the US Fed increasing the interest rates after better employment and inflation figures.
