CASE STUDY: 2018-19 — WHEN THE INDEX ROSE AND MIDCAPS SANK

Over two years Nifty +15.6%, Midcap 100 -19.1% — a 35-point gap

Published by The Retail Trader · DEC 31, 2019 · Case Studies

2018 and 2019 were fine years at the headline level — the Nifty closed positive in both. Underneath that, for midcap investors, this was a two-year continuous bleed. This is the case study that best breaks the 'but the index is up' argument.

THE TWO-YEAR ACCOUNT

2018 and 2019 combined:
• IT — +34.2%
• Bank Nifty — +25.9%
• Sensex — +21.1%
• Nifty 50 — +15.6%
• FMCG — +12.2%
• Nifty 500 — +4.0%
• Realty — -13.9%
• Pharma — -16.4%
• Midcap 100 — -19.1%
• Metal — -28.9%
• PSU Bank — -31.8%
• Media — -47.9%

Nifty +15.6% and Midcap 100 -19.1% — a gap of 34.7 percentage points, in two years. In our midcap-vs-largecap record, 2018 (-18.6 points) and 2019 (-16.4 points) are the two worst consecutive years.

THE NIFTY 500 IS THE CLEAREST PROOF

The Nifty 500 was only +4.0% over two years while the Nifty 50 was +15.6%. The Nifty 500 has 500 companies; its lagging the Nifty by so much shows that the gains had narrowed into a very few big names.

This is what is called a breadth collapse: the index rises because its top 10-15 stocks are rising, while hundreds of stocks below are falling. The screen says 'market at all-time high' and the portfolio is red.

THE HANGOVER AFTER 2017

To understand this, it is necessary to look at 2017: that year Realty was +109.8% (the biggest sector year in the whole dataset) and the Midcap 100 was 18.6 points ahead of the Nifty. 2018-19 was the reverse side of the same coin.

The 2017 leaders and how they did over the next two years:
• Realty — +109.8% in 2017, -13.9% in 2018-19
• Metal — +48.5% in 2017, -28.9% in 2018-19
• PSU Bank — +24.1% in 2017, -31.8% in 2018-19
• Media — +32.7% in 2017, -47.9% in 2018-19

All four out of four reversed. The pattern from our sector rotation study — that leadership does not last consecutively — showed up here in its most expensive form.
