Insights from Ilya

  • It does not pay to take on risk when the overall macro economic trend is negative.
  • When the yield curve occurs, a recession typically happens within 12-18 months
  • Bonds yield has not returned to its previous highs from its current levels of 3-4.5%
  • Stock still offers the highest rates of returns in the long term horizon
  • Shares of companies that do not produce a necessity tends to spike in late stages of a bull market
  • Portfolio allocation horizon
    • short term portion of portfolio which you will need to access within 1 to 2 years should be placed in medium term bonds
    • mid term portion of portfolio which you will need to access within 3-5 years that will likely experience at least one recession should be place partially in stocks and partially in bonds
    • long term portion of portfolio which you will need to access within 10 years that will likely experience at least a few recessions should be placed fully in stocks

Learnings from the market today

During a trade war situation, negative news about one Chinese company listed NASDAQ or NYSE will cause negative price movement of other Chinese companies

  • 17th May 2019 – Baidu poor earnings (-16% price decline) causes Weibo share price decline (-11% price decline)

Negative news about a negative law suit outcome for a semi conductor causes negative price movement of other semi conductor companies

  • Apple evades legal claims by Qualcomm causes price decline in NVDIA (-4%) and MU (-10.6%)

Key trading mistakes during execution


  1. Do not hold a position against general macro events like (Trade) Wars
    • Lesson learned: impact of loss aversion and reversion to mean is muted when trade war is occurring
  2. Don’t double down on your mistakes
    • Lesson learned: it is cheaper to admit mistake and cut losess
  3. Committing too much to a position leaving not much liquidity for later. This forces freeing up liquidity at a loss when new buying signals surface.
    • Lesson learned: it is cheaper to under allocate portfolio to a position upfront.
  4. Entering too late into a buy signal by more than 48 hours.
    • Lesson learned: it is cheaper to forget about it when you are late
  5. Entering too early into a buy signal.
    • Lesson learned: it is cheaper to figure out the support level before entering into position.
  6. Don’t enter into position when there are no buy signals.
    • Lesson learned: it is cheaper to wait for a wave than to get carried away by the anxiety that there will never be a buy signal again in this lifetime.
  7. Not verifying assumptions
    • Lesson learned: Seek evidences to challenge your own assumptions. Lessons could be learned when you dig deeper into pass records to for deeper insights.

Additional insights

  1. Sudden news about macro economic events (Donald Trump tweeting) does follow a lose aversion and reversion to mean pattern.
  2. Gradual news about macro economic events (US passing tariffs on China and banning Huawei) will have a long term negative impact.
  3. Price of REITs are:
    • relatively insensitive to trade wars
    • hyper sensitive to Federal Reserve (expected) interest rate changes
  4. Only execute loss aversion and reversion to mean trades on positions that exhibit bullish trends both at the individual stock level as well as at the SnP level.

Macro economic analysis on US/China 2018/2019 Trade war

The 196 pages of Chinese goods to be taxed by the US governments are spread across 6 categories. Where US manufacturers cannot find alternative sources of supplies, price increase of end product will be expected. 

Based on what was observed in December. The ability of the US government to sustain the trade war is predicated upon the Feds keeping interest rate low. 

Taxed categories include 

  • agricultural produce 
  • textiles
  • chemical compounds
  • hardware parts
  • mechanical parts
  • electronic parts

The December 2018 US market financial meltdown can be attributed to US government tariffs to reduce demand for foreign material supplies from China coupled with Feds interest rate hike to limit capital needed to boost domestic production.

The trade war seems to serve three purposes:

  • Drive up demand for domestic supplies
  • To keep inflation in check the economy grows (traditionally a role played by Fed Interest Rates)
  • Keep China in check.
