One area of the market which I think is a great place to consider long term investments is the healthcare sector. Luckily, there are a large number of quality shares to choose from. Three which have recently been rated as buys are listed below. Should you be snapping up their shares? CSL Limited ( ASX: CSL ) A note out of the Macquarie equities desk two weeks ago revealed that its analysts have retained their outperform rating and increased the price target on the global biotech giant's shares to $230.00. The broker believes CSL is a buy due to being well-positioned to meet the growing immunoglobulin demand thanks to the roll out of its new plasma collection centres. In addition to this, Macquarie appears pleased by the favourable shift in its sales mix to higher margin products such as Idelvion and Haegarda. I would agree with Macquarie on this one and think CSL's shares are a great option for investors.
