Don’t forget a small power strip—ideal for sharing a crowded outlet in an airport, and a simple way to keep all devices close by once at a hotel. (Combine that with a Zolt—which powers a laptop and two devices with a charger the size of a lipstick—and it’s even handier.) Keep a photograph of your luggage and passport on your smartphone; lose either of them, and you’ll be grateful for the reference. Pack a scarf—always. And since calling Nespresso coffee is an insult to baristas everywhere, the best in-room alternate is the Aeropress, a nifty gizmo that’s portable, light, and makes killer morning joe almost anywhere.

We’ve been taught to fear the interference of our portable devices and an airplane’s sensitive electronic systems. And despite being told to turn off our darn phones, four out of ten passengers, it seems, disregard these warnings, since there’s little hard evidence behind claims that electromagnetic emissions from devices can muddle airplane computers. Still, there’s ample anecdotal corroboration, like the flight where a 30-degree navigation error was rectified simply by asking a passenger to turn off a portable DVD player. The issue is still being debated, so if in doubt, flick that Off switch. We might, eventually, long for the days when a chatty seatmate couldn’t make an hour-long phone call.

Stock analysis basics can be broken into two broad categories: fundamental and technical.

Fundamental analysis refers to the study of the company’s annual report, financial ratios, quarterly performance, assets, liabilities, and so on. Analysts and investors look into the financial performance of a company to estimate how it may perform in the future and whether the company is being fairly valued by investors currently. Usually, financial analysis is used to make case for long term investments as any mispricing between a company’s market value and its intrinsic value may take time to be fully understood and for the stock price to adjust

On the other hand, technical analysis involves examining prices and volumes to determine future performance. Technical analysis assumes that all information in the market is factored into the price. It also assumes that the stock prices follow an established trend and patterns seen in the past. It is generally used by short term traders.
