Live: Thursday, Aug. 24, 2017

8/24 – 3:25 p.m. New York time

I entered a position on MRVL and exited positions on LOWMDT and COTY.

I analyzed AVGO but declined to take the trade.

8/24 – 10:55 a.m. New York time

I have updated the exits with results. Also, I am removing GME from my prospects list. It has a high Earnings Surprise Predictor score from Zacks Investment Research, in theory increasing the chance that the price will move beyond the zone of profit.

8/24 – 9:40 a.m. New York time

I have exited LOW for a profit and MDT and COTY for losses.

LOW Analysis

Lowe’s Cos. Inc. (LOW)

Update 8/24/2017: LOW’s earnings failed to attain the Street estimate, coming in at $1.57, rather than the expected $1.62. Shares fell nearly $5 after publication, and then recovered more than half of the loss in a zig-zag movement. I exited at 23.1% of max profit, about $2 below my target.

MDT Analysis

Medtronic plc (MDT)

Update 8/24/2017: MDT’s came in at $1.12 per share, slightly above analysts’ consensus estimate of $1.09. The stock price fell by $3+ over two days. (By the way, am I alone in thinking that such counter-intuitive declines show that earnings estimates have little predictive value to trading?)

Zacks Investment Research forecast a positive earnings surprise, with an Earnings Surprise Predictor score of 0.93.

Shares showed a net decline of 5.1% over my three-day holding period, or a -618% annual rate. The options position produced a -42.2% loss for a -5,137% annual rate.

MOMO Analysis

Momo Inc. (MOMO)

Update 8/28/2017: MOMO met earnings expectations but even so, declined by $9 after publication. It moved in a slight uptrend for three days afterward, before falling another $3 and then on the next day $2 more. 

The best exit strategy would have been to get out quickly. The first day’s fall took it below the breakeven point, and there it remained for the lifespan of the position. Perhaps that’s a good rule of thumb: If a position moves beyond breakeven, perhaps adding a requirement that it open beyond the next day, then exit immediately.

The Earnings Surprise Predictor from Zacks Investment Research gave no indication of a likely surprise, and there was none, illustrating yet against that earnings results are a poor predictor of post-earnings price movements.

Shares fell by 20.2% over seven days, or a -1,055% annual rate. The options position produced a -46.9% loss for a -2,446% annual rate.


MOMO publishes earnings on Tuesday before the opening bell.

I shall use options that trade for the last time 11 days hence, on Sept. 1.

Implied volatility stands at 61%, which is 4.3 times the VIX, a measure of the volatility of the S&P 500 index.

MOMO’s IV stands in the 23rd percentile of its annual range and the 58th percentile of its most recent broad movement.
