Is Google parent company Alphabet in the soup?

Today, I will veer a little off-piste and cover the huge declines in shares of many of the darlings of the US tech boom. These shares form the backbone of many portfolios but will come unstuck as they join the bear trends already in force in many other shares.

The famous four nicknamed 'Fang' have been responsible for keeping the S&P 500 index elevated almost single-handedly in recent months. Some pundits even include Apple, which makes the fabulous five 'Faang'.

These four are the dominant players in their industries Facebook, Amazon, Netflix and Google (now named Alphabet).

From mid-2015 to December, this quartet was up 40% on average, while the S&P 500 index was essentially flat. In other words, without Fang, the market would have been much lower than it was. The average non-Fang share was well into negative territory and that is where the vast majority of investors are invested. And since December, that divergence has grown even wider with the worst start for a new year in financial history.

The mania that drove this famous four to such giddy heights resulted in some incredible price/earnings (p/e) ratios on an almost Shanghai stock exchange (AKA, 'the Chinese casino') scale.

Facebook reached a p/e of 107,Amazon at 952,Netflix at 131,and Google was a steal at only 36.

Is it any wonder they would start falling to earth when the mania faded?

Amazon

After the fourth quarterearnings report was released last month, the earnings per share (EPS) figure was $1 a share. And you had to pay up to $700 for that privilege.

How did the market react to this good report? Of course, it plunged. That's what happens at the end of a long and tired story. For those who believe the news makes the markets, this is all very puzzling.

Since the start of 2015, the shares have rocketed up from $300 to the recent $700 high as investors bought into the story that with its dominant position, the company would at last return profits to shareholders after years of ploughing profits into new ventures.

But it was inevitable that investors would eventually lose patience and they have been voting with their feet in recent days. The shares have lost $200 (28%) so far this year.

But even if you knew nothing about the company, the chart itself would be flashing great warning signals in December. I have a terrific tramline pair working and a huge momentum divergence going into the $700 high.

And when my pink tramline gave way at the $650 level on the very first trading day of the year with a big gap down, that was the clear signal all was not well and provided an escape route, and a shorting opportunity.

The rally into the day of the latest results was the perfect "buy the rumour, sell the news" opportunity.

But here, I am unable to draw highly reliable tramlines and this is the best fit I can make. I like the upper tramline, which now has three accurate touch points when last week's post-results spike hit it (thus validating it as a solid line of resistance).

In trading terms, the shares remain in a bull market that will end when my lower tramline is breached.

Netflix

Here is the post-split daily chart showing upper tramline and two alternatives for my lower tramline. There has been a clear breach of both lower tramlines a bearish sign.

Despite pretty impressive numbers, this was another "buy the rumour, sell the news" event.

Alphabet/Google

The shares poked to a new high at $800, but note that they did not reach my upper tramline. This was a clear sign of weakness, and now with the shares having lost $100 in four days (12%) they are vulnerable to further weakness if the market can close below my lower tramline. They are now testing that critical line of support.

So, has the Fanglost its bite and is Alphabet in the soup? Despite impressive fourth quarterFang results, the shares are declining. And that suggests those results are about at the top, and may not be repeated for a very long time.
