ATK

Atkins... as night follows day: time to short

Coming up to two years ago I sold short in Weir Group (WEIR) with a market cap of £2.4 billion at 2,094p. 
I quickly covered the short about a month or so later at around 2,300p. I closed in the midst of a sharp run up in Weir's price, driven by spurious bid speculation and a short squeeze; short interest at the time was 12%. The market then was also fairly unforgiving for shorts, still being juiced by QE, statements of "whatever it takes" and all that.

JE

Just Eat ... more fine dining than Grub?

Pursuant to yesterday's warning by the US listed online restaurant order and delivery service, GrubHub (GRUB US, market cap $2.2 billion), I sold short a few shares in Just Eat (JE) - market cap £2.9 billion, the UK listed online restaurant order and delivery service. 

DIA

Dialight... more expensive than you think?

Dialight (DIA) has defied gravity of late. I wonder if buyers realise how expensive it likely is. Bloomberg consensus earnings expectations for full year 2015 are set at 21.7p per share. That would suggest DIA trades on a relatively pricey 32x this year's earnings. But it's likely no where near that cheap. 

OPAY

Optimal Payments ... a gamble in China? A sure fire short bet

Matt Earl, the Dark Destroyer, posted this on hs own website two weeks ago. It is a compelling reason to short Optimal Payments (OPAY). It is not historic numbers but future earnings you should focus on. Matt writes: Pursuant to the latest crackdown (see below) by Chinese authorities on online gambling, I've sold short in OPAY the online and mobile payments processor

Apps, Apps, Apps, Apps ...

Each week I will typically see between three to six companies that are either looking to raise capital or that are on the road to raise their profile and expectantly their share price. No doubt I could see more but six is quite enough for me over a five day stretch. 
 

TUNG

Tungsten ... now you see it

A few weeks back, the CEO of Tungsten Bank, Mr Phil Ashdown, moved from that position and departed Tungsten's board to go over to Tungsten's Centre for Intelligent Data Analytics. He is one of a number of board members to depart over recent times. 
 

DIA

Dialight ... here we go again?

I reckon Dialight (DIA) is a grossly overvalued business. All I see is a business capitalised at £255 million, with little in the way of IP, and a dismal record of free cash flow generation. For example, on my calculations it achieved a free cash outflow of £4.6 million in 2013, as compared to a paltry free cash inflow of £2.5 million in 2012.

Hey Tom Genuine question , I’ve been looking more at PBX and am more inclined to want to have a bit of a decent position here -> not large enough to warrant an individual approach to opti but I wonder if there were enough on this board who could offer some liquidity to opti for some cheaper PBX stock vs what I imagine will be a hefty discount if placed out through Reynolds Is this something that’s possible if we had enough interest ?
