Since its initial public offering (IPO) on the 30th January 2015, shares in the fast food restaurant company Shake Shack Inc (SHAK) have almost tripled. Clients at the Hong Kong based wealth management firm, Bliston Asset Management, who were fortunate enough to acquire shares at a Pre-IPO price are now being advised to take their healthy profits after only four months of trading on the open market.

“Here at Bliston Asset Management we are driven by a continuous pursuit of value based investments, which we present to our clients as part of our commitment to deliver sustainable portfolio performance. We were fortunate enough to secure a block of Shake Shack Pre-IPO shares, which were offered to our clients during the third quarter of 2014. The results for our clients since the company listed in January of this year have been outstanding. Needless to say that in this instance our clients are pleased with our recommendations,” commented Bliston Asset Management’s Senior Equities Analyst.

In the competitive fast food restaurant industry, capturing market share from more established players has historically proved to be a difficult obstacle to conquer. However with strong quarterly earnings recently reported, it appears that Shake Shack is managing to prosper through a growth stage as its global restaurant presence has recently expanded to 66 functioning establishments.

However, as shares in the Shake Shack peaked at $96.75 last week, the company announced diversification strategies that would incorporate chicken products into its beef-heavy menu pricing the company at a staggering $3.3 billion or $50 million per operating restaurant.

“If we look at the fundamentals it is hard to argue that the company is not dangerously overpriced. At $50 million divisional cost per restaurant we only need to compare this to Chipotle Mexican Grill’s (CMG) divisional cost of $10.5 million. Although Shake Shack has exceeded analyst expectations for their first two quarters since listing, we feel that investors have been riding a bull that is about throw their gains off the back of an incredible run,” continued Bliston’s Senior Equities Analyst.

“Since bringing a select number of our clients into this stock we have continued to remain positive on Shake Shack’s short-term potential. However as retail investors who turned up late to the party seek to capitalize on the growth story, our valuation concerns have weighted the stock towards a sell position and advise our clients to take immediate action by releasing their profits in the stock.”

As shares in the company fell around 10.5% last week, analyst consensus predicts that the fall is likely to continue as the lockup expiration period for holders of common shares expires on the July 29th, forcing a further influx of investors looking to get out ahead of their principle investments.
